To all whom it may concern V Be it known that 1,.VALENTINE O. ZAHN-ISER, a citizen of the United States, residing at Washington, in thecounty of Washington and State of Pennsylvania, have invented certainnew and useful Improve:

ments in Band-Wheels; and I do declare thefollowing. to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which. it

. appertains to make and use the same.

My invention relates broadly to improvements in band wheels and moreparticularly to those of the type commonly employed in connection withwell drilling machinery.

The object of the invention isto provide a wheel of the herein set forthtype which may be simply and inexpensively manufaotured yet onewhichwill be extremely rigid and eflective in operation. I

In carrying out the above end,'the invention aims to provide a number ofattaching elements whereby the arcuate rim sections of a band wheel maybe removably secured in position. is With the above and other obyectsview,

- of attaching element; Figs. .6 and .are respectively an inner side andan edge view wofanother form of attaching member; and Fig. 8 is an innerside viewpf one of the hub members.

In the accompanying drawings, ,1 have shown my improved wheel ascomprising a which are here pair of hub members shown asrigidly mountedand spaced upon a shaft 2, a number of spokes 3 radiating from said hubmembers, a number of rim attaching members 4 secured to the outer endsof said spokes and designed for the attachment of the rim 5, and anumber of similar attaching members 6 secured to the sides of thespokesand designed for. the at-" tachment of a rim 7 lhe hub members 1 eachcomprise a ring" shaped body portion 8 upon whose periph- BAND-WHEELPatented June 15, rule.

Application filed my 13, 1914. Serial No. 850,797.

ery a flange 9 is formed, a number of pairs of parallel ribs lOfbeingformed on either the inner or outer sides of the flanges 8 and beingdesigned to receive the spokes 3 which may be of channeled or angle ironor may be in the form of flat metal bars as shown in the drawings,suitable bolts or rivets 11 being passed through the inner ends of thespokes and through the flanges 9 for the purpose of rigidly securing theformer to the latter. By an inspection of Fig. 2, it will be seen thatthe pairs of spokes 3 converge from their inner toward their outer ends.

The extreme free ends of the spokes3 are secured by'means of bolts orother suitable fasteners 12 to pairs of lugs 13 which extend radiallyinward from a number of arcuate attaching plates 14, said lugs andplates constituting portions of the members 4. It will be noted thateach plate 14 is here shown as ofrectangular formation and as beingprovided with a' pair of inwardly extending, lugs 13 which are providedon their outer edges with radial ribs 15 which embrace the spokes 3 asclearly set forth in the drawings, It will be further noted that .eachplate 14 is provided, upon its periphery, with a longitudinallyextending flange 16 which extends throughout its length and with atransverse flange 17 which extends throughout its width and intersectsthe flange- 16 at substantially its center.

With the spokes and the members 4 in the above set forth' positions,a'numberof arouate rim sections 18 are secured to said members 4, theopposite ends of said sections 18 contacting with the transverse flanges17 while their inner curved surfaces rest against the periphery of theplates 14, their inner end-portions, lying parallel to their outeredges, being notched as indicated at 19 and bearing against the flange16, suitable fasteners 20, here shown in the form of bolts, being passedsaid rim sections 18 and through openings 21 through-the end portions offormed in the flanges 16 whereby to rigidly securesaid rim sectionsinposition upon said plates. If the sections 18 be of greater width thanthe width of the portion of the plate 14 upon which theyrbe'ar, asillustrated in the present case,

may be notchedas at 22 for the reception of the ends of said sectionsthe transverse flanges 17.

By the above set forth construction, an

'grally or otherwise with the peripheries of the arcuate plates 14'. Inthis case,it will be noted that the flanges 17 are of less size than theflanges '17 and that their upper edges incline downwardly and outwardlyas clearly seen in Figs. 2 and 7 The parts just described as well asparts now to be described constitute portions of the attaching members 6hereinbefore mentioned. 7

For the purpose of rigidly securing the plates 14' in fixed relation tothe spokes 3, the flanges 16 are provided with radial ribs 15 whichstraddle said spokes 3,suitable bolts ,or other fasteners 12 beingpassed through said spokes and through the outer edge portions. of theplates 16. When the parts are thus assembled, a number of arcuate rimsections 18' constituting the rim 7, are secured in position with theirinner curved surfaces contacting with the periphcries of the plates 14while their ends are notched as indicated at 22' in Fig. 2, for thereception of the flanges 17, suitable transverse bolts 20 being passedthrough the rim sections 7 and through apertured ears 21' which areformed on the radial edges of the plates'16, whereby said sections 18are forced into binding frictional contact with I I the flanges 16. Ifdesired, a number of inclined bracing ribs 23 may be employed .on theinner curved surfaces of the plates 14,

said ribs contacting with the spokes. as clearly seen in Fig. 2.

I 'The construction just described constitutes the tug wheel abovementioned and whose periphery is preferably grooved as indicated at 24in order .to receive a cable (not shown) which is commonly, employedwith devices of this character for the purpose of driving the bull wheel(not shown).

" connection with the accompanying drawings it will be seen thatalthough from a casual G inspection, the construction of the attachingmembers 4 and 6 seems to be vastly different,

.each of said members comprises an arcuate plate, a longitud nal flangeformed on the periphery thereof and a transverse flange abutting saidlongitudinal flange and united thereto and to the periphery of saidplate.

Having thus described my invention, what I claim as new and desire tosecure by Let- V ters-Patent is:

1. The combination with a hub and a plurality of spokes radiatingtherefrom, of a plurality of arcuate plates secured to said spokes andeach having a longitudinally extending flange formed integrally with itsperiphery and a transverse flange likewise formed integrally with saidperiphery and with said longitudinal flange, a plurality of arcuate rimsections having their inner curved surfaces in contact with theperipheries of said plates, the end portions of said sections abuttingsaid transverse and longitudinal flanges, and means for securing saidsections in position.

2. The combination witha hub' and a plurality of'spokes radiatingtherefrom, of a plurality of circumferentially spaced arcuate plateseach having an attaching lug extending radially inward from its inner'curved surface, fasteners passing through the free ends of said spokesand'throughsaidlugs, the plates also having longitudinal flanges formedintegrally with their peripheries at substantially their centralportions, and

transverse flanges likewise formed integrally with their peripheries andwithtlie longitudinal flanges at substantially their central portions, aplurality of arcuate rim sections contacting on their inner curvedsurfaces with said arcuate plates, said sections having their ends andtheir inner side portions contacting respectively with said transverseand longitudinal flanges, and fastening means for securing said rimsections in position. Y

3. In a device of the character described, a plurality of spaced arcuateplates each having a longitudinal and a transverse flange formedintegrally with its periphery, said flanges intersecting each other atthe center of the plate, a number of arcuate rim sections having theirend portions contacting with said flanges'and said plates, means forsecuring said sections in positiomeach of the plates also having a pairof'lugs pro jecting radially inward from their inner through the latter1 and through the spokes, and a hub from i p which said spokes radiate.From the foregoing description, taken in l, The combination with'a huband a number of spokes radiating therefrom, of

two series of arcuate plates secured to said spokes, one series beingsecured to the outer ends of the latter and the other series beingintegrally with their peripheries, 'said flanges being also integrallyunited with each other at substantially their ceiitralportions, a numberof arcuate rim sections having their opposite end portions contactingwith the plates of the outer series and with the flanges thereof, otherareuate rim sections contacting with the plates of the other series andwith the flanges thereof, and independent means for securing the twosets of arcuate rim sections in elfect-ive position 5. A wheel of theclass described compris ing a hub, aplurality of spokes radiatingtherefrom, a plurality of rectangular arcuate plates, each having a pairof lugs formed 1n- I tegrally with its inneucurved surface, said lugshaving parallel ribs formed integrally with their opposite edges, theouter ends of the spokes being located between said ribs and in contactwith said lugs, bolts passing through said lugs and through said spokes,the areuate plates alsohaving longitudinal outwardly extending flangesand rectangular transverse outwardly extending flanges formed integrallywith their peripheries and likewise formed integrally with each other,each plate having one longitudinal flange and one transverse flangewhereby to provide each of said plates with four angular seat-s, arcuaterim sections whose opposite ends rest within said seats, and boltspassing through said ends of the rim sections and through saidlongitudinal flanges.

In testimony whereof I hare hereunto set my hand in presence of twosubscribing witnesses.
